Description
The MMCX (Micro-Miniature Coaxial) male connector is a high-performance RF component valued for its exceptionally small footprint and 360-degree rotation capability after mating. This variant is specialized for the 2.5mm to 3mm cable class, specifically optimized for high-performance LMR100 and high-temperature RG316. The snap-on coupling mechanism allows for quick, tool-less mating, making it ideal for high-density electronic assemblies where space for threaded connectors is unavailable.
As a male interface (plug), it features a precision center pin and an internal spring-contact sleeve designed for secure engagement with MMCX jacks. This connector utilizes a hex-crimp termination system for the outer conductor, providing a high-strength mechanical bond and excellent strain relief for flexible coaxial lines. Manufactured with a gold-plated brass body and premium PTFE (Teflon) insulation, it delivers consistent 50-Ohm performance and reliable operation up to 6 GHz, ensuring signal integrity in sophisticated IoT and broadband devices.
Key Technical Advantages
-
Micro-Miniature Snap-On Design: The ultra-compact interface enables high-density packaging on PCBs and allows the cable to rotate freely to prevent kinking and mechanical stress.
-
Thin-Gauge Cable Match: Specifically calibrated for the 0.100″ to 0.110″ OD cable family, ensuring a precise mechanical fit and optimized electrical transition for LMR100 and RG316 lines.
-
Secure Crimp Termination: The hex-crimp sleeve provides a robust 360-degree grip on the cable braid, offering superior pull-off resistance and high EMI/RFI shielding.
-
Low VSWR Performance: Precision-machined internal components and gold-plated surfaces ensure minimal signal reflection and low insertion loss across microwave frequencies.
-
Superior Corrosion Resistance: Features heavy gold plating on the body and center contact to maintain excellent electrical conductivity and reliability in various environmental conditions.
